Just the tip..right? Your sis' reluctant and shy friend let's you convince her to get naked in front of you... as your cock get's harder I can't help but notice. You like seeing me like this, don't you? You slowly convince me to lie back and take justttt the tip of your hard cock inside. But before we know it, we're fucking and craving orgasm!! Please cum inside me while I orgasm on your cock.. I need it so bad! Your sis can never find out...
